Abstract : The transportation problem holds significant importance within the field of operations research, with a critical objective of minimizing transportation time to optimize fleet efficiency. This endeavor yields numerous benefits, including cost savings, enhanced customer service, increased competitiveness, a resilient supply chain network, and positive implications for sustainability and the environment. This research paper addresses the complex multi-dimensional transportation problem by focusing on the transportation fleet of a soft drinks company in Egypt. Our primary goal is to reduce the total time allocated to fleet movement by implementing a redistribution strategy involving different types of trucks sourced from various origins and destined for specific locations. We have devised a solution methodology using Lingo code to tackle this challenge. The optimal solution is then compared to the current situation based on the company's existing records. Our approach has yielded impressive results, demonstrating a 15% reduction in daily fleet movement time, resulting in over 55,000 saved movement hours over one year (considering 250 working days). These outcomes underscore the efficacy of our proposed strategy and its potential to deliver tangible benefits to the transportation operations of the soft drinks company..

Abstract : E-Commerce Web Applications testing has become a complex and tedious task because of their growing nature as well as increasing number of their probable customers. To ensure that these web applications are dependable, reliable testing tools as well as severe testing methods are required. In this paper various methods for web application evaluation have been discussed. The literature also addresses various tools used for performance testing of e-commerce web applications along with several parameters for performance testing. Results and inferences obtained after execution of performance tests on one of the well know e-commerce web application amazon.in using Apache JMeter Tool have also been presented. It is important to choose an appropriate testing tool for the purpose of testing a particular web application. The focus of this study is to review state -of -the- art performance testing tools so as to help testers and researchers to compare them and choose the best tool suitable for a particular purpose..

Abstract : In this research, natural fibers are used as composite materials as sound absorbers because they can reduce noise. Sound absorbers from natural fibers can reduce noise. It consists of a combination of coconut fiber and banana midrib as a filler and PVAC glue as a matrix. The variations of ratio of the coconut fiber and banana’s mid ribs are 1:1, 2:1, 1:2. To bind the material, PVAc glue was implemented, with its thickness ratio= 2 mm, 3 mm, and 4 mm. The sound-absorbing coefficient value refers to the ISO 11654:1997 standard. The final result shows the value of the sound absorption coefficient= 0.15 on a ratio of 1:1 with a thickness variation of 3mm, 4mm. It is categorized in C-grade. At a fiber ratio of 2:1, with a thickness of 2mm, it is categorized as E-grade. In the ratio of 1:2 fiber with a thickness of 2mm is categorized in E-grade, and 4mm is categorized in D-grade..

Abstract : This decision was made in order to choose between the got crops leguminosae Indigofera zollingeriana (Iz) and Brachiaria humicola (Bh), a tropical grass. The purpose of this consideration was to investigate the apparent magnitude of this received change in light of bearing limit and abandonment. The plan for this test was completely random, and for combination planted (C), it used a combination of four drugs from the planted area: C1, Iz, with dimensions of 1.0 m x 1.0 m and Bh, with dimensions of 0.5 m x 0.25 m; C2, Iz, with dimensions of 1.0 m x 1.0 m and Bh, with dimensions of 0.5 m x 0.5 m: C3, Iz, with dimensions of 1.0 m x 1.5 m and Bh, with dimensions of 0.5 m x 0.25 m; Using the analysis of variance and the HSD test, the data were analyzed for C4, Iz, which had 1.0 m x 1.5 m, and Bh, which had 0.5 m x 0.5 m. Economic profit and the Land Equivalent Ratio (LER) were the variables that were measured. (P 0.01) The outcomes appeared to be substantially different. The total LER and economic benefit are highest due to the improved grain yields of intercrop in C4. Iz covered crops with established areas of 1.0 m x 1.5 m and Bh with established areas of 0.5 m x 0.5 m may be considered to have the best advantages in terms of yield and conveying limit..

Abstract : In The present work a circular inspired dodecagon shaped monopole patch antenna having a compact size of 30x22mm2 in MIMO configuration has been proposed. The proposed antenna is covering entire UWB band (2.-11 GHz) having a better isolations approx. -25 dB in the entire operating band, also it exhibits a better performance in terms of ECC and Diversity gain. The simulated and measured response are in a very close agreement to each other..
